A Brooklyn hit-and-run driver, accused of plowing a Jaguar into a college student – costing the victim her leg – was found with a crack pipe while sitting in a holding cell after turning herself in, prosecutors said.

Donna Dashosh was arraigned in Brooklyn Criminal Court and held in lieu of $50,000 bail yesterday – the same day she was slapped with a civil suit for being “reckless and negligent.”

Her victim, Adriana Melnichenko, 21, is “doing remarkably well,” according to her lawyer, Ken Fink.

The Brooklyn College student had surgery yesterday, this time for fractures to her arm.

“She does not remember much about the accident,” Fink said. “She saw a white car backing up at a high speed, and the next thing she knew, EMS was working on her.”

Melnichenko was standing near the Sheepshead Bay Road subway station at East 15th Street on Sunday evening when Dashosh jumped the curb as she backed up in her 2001 Jag, police said.

Melnichenko was pinned to a stanchion as horrified onlookers ran to her aid, prosecutors said.

One witness said he tried to get Dashosh, 45, out of the car and smelled alcohol on her breath.

“Get the f- – – away from [me],” Dashosh told the man before she allegedly drove off as pedestrians were lifting the car off of the young woman. Then she ran three red lights, prosecutors said.

Melnichenko was left bloodied and mangled – so much so, doctors at Bellevue Hospital in Manhattan had to amputate her leg.

The accident came just as Melnichenko was getting ready to graduate, Fink said, adding that she is set to start at Hofstra University in the fall for a master’s degree in education.

Dashosh turned herself in to cops yesterday to face charges of drunken driving, assault and leaving the scene of an accident.

She was also slapped with a drug-possession charge when an officer found her holding a crack pipe as she sat in a cell.
